Baghdad Batteries Lost Forever?

Baghdad's National Museum in Iraq houses some of the world's finest treasures dating from the beginning of recorded civilisation. In 2003, during the chaos of war in Iraq, the National Museum was looted. The tragic loss may include more than just priceless vases, seals and statues however. Before the war started, BBC reported on the museum's unusual 2000-year-old artefacts known as the "Baghdad Batteries".
